(Do not switch between the modes directly without an allow.) 2 : The all modes can be switched to the stop mode or the wait mode and return to the source mode when the stop mode or the wait mode is ended. 3 : Timer operates in the wait mode. 4 : When the stop mode is ended, a delay of approximately 1 ms occurs by connecting prescaler 12 and Timer 1 in middle/high-speed mode. 5 : When the stop mode is ended, a delay of approximately 0.25 s occurs by Timer 1 and Timer 2 in low-speed mode. 6 : Wait until oscillation stabilizes after oscillating the main clock XIN before the switching from the low-speed mode to middle/high-speed mode. 7 : The example assumes that 10 MHz is being applied to the XIN pin and 32 kHz to the XCIN pin. φ indicates the internal clock. |
